Abstract

"VáLVULA DE INJEçãO DE COMBUSTìVEL". A invenção refere-se a uma válvula de injeção de combustível (1), que pode ser instalada em um furo de recepção (39) de uma cabeça do cilindro (1b) de uma máquina de combustão interna que apresenta um anel de vedação (1a) disposto no furo de recepção (39) na periferia em redor da válvula de injeção de combustível (1). O anel de vedação (1a) apresenta uma superfície de contato (40) em forma de esfera parcial em direção à válvula de injeção de combustível (1) que encosta em uma correspondente contra-superfície (40a) em forma de esfera parcial da válvula de injeção de combustível (1)."FUEL INJECTION VALVE". The invention relates to a fuel injection valve (1), which can be installed in a receiving hole (39) of a cylinder head (1b) of an internal combustion machine that has a sealing ring (1a ) arranged in the receiving hole (39) on the periphery around the fuel injection valve (1). The sealing ring (1a) has a contact surface (40) in the form of a partial ball towards the fuel injection valve (1) that touches a corresponding counter-surface (40a) in the form of a partial ball of the fuel valve. fuel injection (1).
